Specification forming 'part of Letters Patent No. 47.696, dated May 16, 18155.

To all l'114771.'0111/ it may concern:

-Be it known tirati, LYMAN R. BLAKE, of Boston, county of Sui'olk, and State of Massachusetts, haveinvented an Improvement in Constructing-Boots and Shoes; and I do here by declare that 'the following, taken inconneetion with 'the drawings which accompany and' form part nl* this specification, is a de' scrlption of my invention suiiieient to enable those skilled in the art-topractice it. g

1n thefmanufaeturc oi' boots and shoes it is ai desideratum to so employ an'inner 'sole that the union of the vamp with the outer or Wearing sole shall not depend upon the inner sole, and so that `the inner sole has 'no function other than that of means for temporarily securing the vamp -in proper position tol receive the outer sole, and of filling to make a suita-V "ble surface for the foot to rest upon. In boots and shoes previously made, employing an, in ner sole to which the vamp was secured or lasted, this sole also. performed an important part in maintaining the integrity of the structure, inasniuohas that the union of the ram p with the o'uter or wearing sole depended as `niuchupon the inner sole as upon the other parts.-

To so construct a boot or shoe that the in ner sole shall have no other functiomthan the temporary onel of means for lastingland the permanent one of filling is the object of my invention,l which consists inconstructing a boot or shoeu'ith the outer sole and vamp united by stitches or other connecting device or devices passing directly through them-from the outside tothe inside ofthe article, the inner sole being made so much narrower and shorter than the outer or wearingsole that theI connections which are employed to unite the Vamp and outer sole shall 4not pass into the inner' sole.

Figure 1 is a cross section of a boot or shoe constructed in accordance with the process which constitutes my invention; and Fig. 2 is a. similar vieur `of the now well-known construction descrihed in the United-States Patent No. 29,562, dated August 1'4, `1860.

In Fig. 1 it'will he seen that the size of the inner sole is suchas to-i'all short of the device sole, while in Fig.. 2 the inner sole is of such size that the seam passes throughnt.

In Fig. 2 the integrity ot' theshoe depends which unites the vamp and louter or wearing upon 4the inner sole as much as upon the vamp and outer sole; hence it is needed that the inner sole should be of leather, or other equivalent material, and of good quality, for if in wear the inner sole gives way or is cut through by the stitches then the seam is loosened and the stitches either eut o r rip.

In the construction shown in Fig. 1 less Astock is required for the inner sole, and it may be made of Veryrheap material, .the waste from paper-box factories answering as well as leather, while its cost is a mere trifle.

In Fig. 1 the wholeiinner sole may be removed, and yet the `forni und integrityof the shoe will be uninjured, and the place of the inner 'sole may be supplied by any suitable loose material. 4

. In both figures'thc lasting-tacks are shown asv passing through the vamp and as clinched in theinner solo. y

In'llig. 1 the inner sole may serve the mere temporary purpose ot' lasting only, being made of leather or other suitable stout material, which, after the vamp and sole are prope'rly fastened together, ina-y be forcibly torn out and used again and again for the purpose of lasting. After the temporary inner sole is thus removed the shoe. must be placed on a metal-bottomed last and hammered or rolled on the surface of the sole to clinch or embed into its inner surface such .of the lasting-tacks Y as, do not tear 'out ofthe vamp 'in the removal ofthe inner sole. This removal of the inner sole is not dillicult, the only bond of union between it and the vamp being ay few slight lastingtacks, andits removal does not in thel least impair the integrity oi' the structure of the shoe, which remains as perfect as before the inner sole was removed.

ln Fig. 2, where the inner sole forms an integral part-of the structure, it could only be torn out with the greatest diileulty, and when removed thestitehes uniting the vamp and sole would all be loose and the shoe would be in 'a worthless condition.

In Fig. 1 Vthe conneeting device lsshown on oneside as extending to the outer surface,

and on the other side as driven from the outer surface and beyond the plane thereof into a channel, the flap of which is turned over to close the channel and present a iiuished cute-r surface.
